When optical signal is detected, current, which runs through photo diode 1, is amplified by transistors 8 and 9, which currents are added and result is base current for transistor 7. Signal current of transistor 7 serves as biasing current at resistor 12. Potential at base of transistor 2 is decreased and collector current at transistor 2 is increased. This results in decreased impedance at resistors 16 and 17. Biasing voltage of current amplifier at transistors 7-9 is increased in order to balance increased impedance at emitter junctions of transistors 7-9 and to keep constant value of negative biasing of photo diode 1 and potentials at its terminals with respect to power supply lines and device wiring.
